There has been a growing interest in monitoring underwater mediums for scientific exploration, commercial exploitation, and attack protection as it contributes for human well being. Industries are increasingly interested in technologies like wireless sensor networks. Under water sensor network consists of a variable number of sensors and vehicles that are deployed to perform collaborative monitoring tasks over a given area. Efficient information exchange via wireless communication using physical waves as the carrier among nodes in an underwater sensor network.

OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers and sent simultaneously in time. The result is an optimum usage of bandwidth. A set of orthogonal sub-carriers together forms an OFDM symbol. To avoid ISI due to multi-path, successive OFDM symbols are separated by guard band. This makes the OFDM system resistant to multi-path effects. Although OFDM in theory has been in existence for a long time, recent developments in DSP and VLSI technologies have made it a feasible option. This paper describes the VLSI implementation of OFDM in details. Specifically the 802.11a OFDM system has been considered in this paper. However, the same considerations would be helpful in implementing any OFDM system in VLSI. OFDM is fast gaining popularity in broadband standards and high-speed wireless LAN.

This Nanotechnology Center was being built in the spring of 1990, as Eric Drexler was midway through a hectic eight-day trip, giving talks on nanotechnology to researchers and seeing dozens of university and consortium research laboratories. A Japanese research society had sponsored the trip, and the Ministry of International Trade and Industry MITI) had organized a symposium around the visit a symposium on molecular machines and nanotechnology. Japanese research was forging ahead, aiming to develop "new modes of science and technology in harmony with nature and human society, a new technology for the twenty-first century.

In the early hours of 26'Th December 2004 the world witnessed one of the most devastating natural disasters in the recent times causing the death of nearly 80,000 people.Tsunami a powerful fast moving wave by an under sea disturbance.If we had sufficient warning system to give indications ,then we certainly could avoid this much of destruction. With the present technology, even a slight undersea disturbance can be detected by special detectors placed on the sea floor.These signals are picked by the surface buoy, which sends data to satellite for further distribution to ground stations.

Can virus infect the mobile phones? It is a million dollar question that has no answer up to now. The chance is increasing day by day and recent hoax virus, Spam SMS worms is an evidence of it. Due to the financial aspects associated with wireless communications, this subject is under through research now.

This system is used in hospitals, because the patients in the ICU need a constant monitoring of their body, Respiratory Temp, Saline Status and ECG. Our project is a working model that incorporates sensors to measure all these parameters and transfer it to the computer, so that the patient condition can be analyzed to by doctors in any part of the hospital wherever they are. thus it reduces doctor’s work load and also gives more accurate results, wherever there is an abnormality fell by the patient, we have also incorporated saline monitoring system which gives an alarm when the saline bottle about to empty.

Electronics and computational techniques are increasingly being used to analyze biological cells to diagnose diseases and develop methodologies to cure diseases inside the body. One such technology is ‘Nanotechnology’. The paper emphasizes on the best and effective utilization of Nanotechnology in the treatment of cancer. The design of nanodevice is based on the constant study of cancer cells and nanotechnology.

The wireless communication and networking on a large scale is carried out through satellites. Inter planetary communication is also made possible due to satellite technology. The various kinds of space debris or space junk that are revolving around our earth in an orbit possess a threat to the satellite communications. Infact, these particles whether tiny or big are on their way to destroy the whole system of satellites and space stations orbiting around our globe in the near future. This deadly debris must be eliminated in order to have a complete access to our earth orbiting satellites. The concept of light pressure exerted by laser beams provides a valuable tool to eliminate these particles. The following section gives an idea of reducing the space debris and also eliminating them.

In the present day scenario of Embedded applications in Wireless Technologies Smart Dust Mote sensors is exploring the limits of autonomous sensing and communication by packing an entire system into a cubic millimeter at a relatively low cost. These volumetric constraints correspond to energy constraints on the system. Therefore, the mote "intelligence" must operate on the absolute minimum energy while providing necessary features. The mote can be partitioned into four subsystems:

Conventional register transfer level (RTL) debugging is based on overlaying simulation results on structural connectivity information of the hardware description language (HDL) source. This process is helpful in locating errors but does little to help designers reason about the how and why. Designers usually have to build a mental image of how data is propagated and used over the simulation run. As designs get more and more complex, there is a need to facilitate this reasoning process and automate the debugging .In this paper, we present innovative debug techniques to address this shortage in adequate facilities for reasoning about behavior, and debugging errors .Our approach delivers significant technology advances in RTL debugging; it is the first comprehensive and methodical approach of its kind that extracts, analyses, traces, explores and queries a design’s multi cycle temporal behavior . We show how our automatic tracing scheme can shorten debugging time by orders of magnitude for unfamiliar designs .We also demonstrate how the advanced debug techniques reduce the number of regression iterations.
